With your high-performance ultrasonic generator, you can avoid annoying and unsightly cat paw prints on your freshly washed car and effectively protect yourself from costly repairs caused by marten bites. The built-in special speaker with a painted, moisture-protected membrane emits a sound at 22 kHz that is inaudible to humans, driving away unwanted animal visitors. Thanks to battery power, you can quickly change the location of your protection device as needed. This way, pesky pests are effectively kept away from attics, garages, carports, outbuildings, and sheds. The powerful device can even be used in the garden. Includes a function control LED.
